pipe 20 and stand-pipe 23. Assuming noiv that the supply of liquid to said vessel luis risen to a level above the level ol ihe upper open end ofthe stand pipe 522-5, it will he observed that by ceasing the pumpingl operation and openingr the valve :26 `the amount of gasolene ahove"said level will he quickly drained back into the storafre` tank through standpipe 23, and pipes 2o and 20, Thus it will be observed that a common supply and overflow pipe for the attachment provided,therel y greatly simplifying the ecnstruction and rendering; it comparatively cheap to manufacture.

A suitable outlet 27 for the'rneasurirgvessel is also provided in the base plate i8 thereof, and to this outlet is attached the usual delivery hose provided with the usual discharge nozzle 28a and cubo?? valve. 9.8i'. By means of this flexible. delivery hose the supply of gasolene in the measuring ves sel, after the quantity thereof has been definitely determined, may he conveyed into the fuel tank of an automo'pile or other receiving receptacle. At 29 there is illustrated `a small drain `pipe. also provided with a valve 29,.said'pipe being connected to the supply,7 pipe 20 at one end and to the measuring vessel at its other end. B v means of this drain pipe and associated valve any portion of the liquid within the measuring vessel may loe drained hackjnto the sten age tank, thus rendering it possible to measure smallerqu'antities of gasolene than are measured by the normaloperation of the device. 1t Willalso be observed. in the eve-nt the fuel tank will not hold the full measured quantity of gasoline, that the portion which remains in the measuring vessel aier the valve 28h has been closed may be readily and quickly drained back to the storage tank hv means of the drain pipe just described. The measuring, attachment is supported preferably at a distance alcove the pump by means of a suitable standard 30, whieh seeurelvv fastened to the base plate 18 of the measuring vessel at one end, and the other end thereof being designedto it the top of the pump. so that the entire attachment may be rigidly and firmly attached in position, substantially as shownd in Fig. l of the drawings.

*The glass cylinder of the measuring vessel is preferably' surroundelsby a suitable open niesh Wire cage 3l, so astio protect the saine from breakage. While at the saine time permitting the gasolene, as the saine rises and falls Within the measuring vessel, to he clearly observed.

In the embodiincnls'of the invention'illustrated in the drawings the measuringA vessel is preferablyrv lgraduated. as shown at 3Q. to read in terms of gallons` the full capacityv or' the measuringT vessel, as limited h v the. position ol the stand-pipe thcreimlieing. iu

the form shown, ve gallons. nvxcess of this amount m515v he Lpaiclvlv returned lo the storage tank in the manner ahove pointed ont.

ln Fig'. l ol' the drawings a slightly molliiicd foral of measuring attaclnncnl, is illustrated, said attachmentheingf hotter adapted for usc in connection with certain types of dispensing pumps other than the one shown in Figi. ln this forni of measuring' attachment a standpipe Illis provided which is used onlias an overflow pipe, 'the liquid being; pumped into thc measuring; ves .sel through a supply: pipe 'll. which terminates adjacent the inner surface of ihc base plate 35 of the vessel. and is provided with suitable openings, so that thc liquid nia \.v readil)Y dou' from said pipe into the vessel. The other features oi: this construction are substantially .the saine as described in counection with the preferred embodiment oi he invention. and further description of this modification muy. therefore, hc dispensed with.

ln using the zuitacluneut shown in Figi. l. all of the. valves are closed. and lhe pumping mechanism then actuated, vvhcrcruion the gasolene or other liquid will he supplied to the measuring vessel through the aperturcd cap 2l on the upper end of ihe stand-pipo llpon the gasoienc rising;` to a level above the top oi" the pipe Qi'l. he pumpingA .operation stopped and' the valve 2G provided in the supply pipe Q0 opened. hcrcbv drainingV the excess liquid back into (he ,storage tank. rlie nozzle 2S of the delivcr hose is then inserted into thc fuel tank of 'the automobile. and the valve t28" opened. whereupon the measured quanti)v oit ,grasolene drains into said tank. The purpose of the valved drain pipe 29 has already been pointed out. The nieasuringoi `Jasolenc bv incans olijthc measuring attachment showin in Fig. Ll is accoinplised in substantially ib" same manner as just described in connection with thel attachment illustralcd in Fig. l. substantially the onliY difference in lhi'f'lu'o operations being that the measuring vessel of the modification. is lilled bv means` oi' a pipe separate and distinct from the over flow pipe.

It ivll, of course. be understoml that thc measuring" attachment herein described is not necessarilyv intended to take the placc et Jhe measuring mechanism of the punu out is merely designed to indicate visuallv the correctness oi the quantities delivered bv the latter. Thus the numerous vvell-l novvii conveniences and advantages of thc zneasur ing punlp mechanism may be retained. ivliilc at thc .same time the additional :ulvautagcs l, f

provided bv the auxiliary measuring aflach ment herein described are` also obiaiiuul. llhile. as above stated. thc nieasurinslf ab iachnicnt herein described is not incnded lo talee the place of the purnp measuring mech- Leyenda u anism, yet, if so desired, in view of the .tact

that the'present attachment provides an eiticient and accurate measure' forthe gaso f lene, such pump-measuring mechanism Imay 5f be discarded. It will be observed, in the ,event both the pump measuring mechanism and the present attachment are employed, however, that the tivo operate Wholly independently, and that during such operation iu each serves as a check upon the other.

It is obvious that various changes and modifications may be made in the embodi ments of thel invention herein illustrated and described without departing from the spirit i5 ot the invention, and accordingly it is'not desired to limit the invention, except Where limitations appear in the appended claims.
